You'll get good exercise for your right thumb with the old Homelite. I have a soft spot for them, though -- first saws I used.
Check the bar for pinching on your Husky. Is it overheting in a particular spot? Is the oil hole in the bar clear all the way through to the chain -- poke a wire up all the way throught the hole on the side -- it should come up through the chain channel.
I've seen guys with oil dripping off their saws and dry chains, not realizing the channel was clogged with sawdust, swearing their oilers worked fine.
ps.
One good check also is to point the saw at a piece of cardboard propped up about a foot away and gun it full throttle. Oil should splatter onto the cardboard if the chain is getting oil
